Subsequent preamble-less early data transmission

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an early data transmission (EDT) communication including an indication associated with subsequent EDT communications. The UE may transmit a subsequent EDT communication after transmitting the EDT communication, wherein the subsequent EDT communication is transmitted in a transmission occasion based at least in part on the indication. Numerous other aspects are described.

What is claimed is: 
     
         1 . A user equipment (UE) for wireless communication, comprising: 
 one or more memories; and   one or more processors, coupled to the one or more memories, configured to cause the UE to: 
 transmit an early data transmission (EDT) communication including an indication associated with subsequent EDT communications; and 
 transmit a subsequent EDT communication after transmitting the EDT communication, wherein the subsequent EDT communication is transmitted in a transmission occasion based at least in part on the indication. 
   
     
     
         2 . The UE of  claim 1 , wherein the subsequent EDT communication is associated with the EDT communication, and the indication indicates that the UE is to transmit the subsequent EDT communication. 
     
     
         3 . The UE of  claim 1 , wherein the EDT communication includes a first non-access stratum (NAS) packet data unit (PDU) and the subsequent EDT communication includes a second NAS PDU. 
     
     
         4 . The UE of  claim 1 , wherein the EDT communication includes a first segment of a non-access stratum (NAS) packet data unit (PDU) and the subsequent EDT communication includes a second segment of the NAS PDU. 
     
     
         5 . The UE of  claim 1 , wherein the EDT communication includes an identifier associated with data carried in the EDT communication, and the subsequent EDT communication includes an identifier associated with data carried in the subsequent EDT communication. 
     
     
         6 . The UE of  claim 1 , wherein the EDT communication includes a radio resource control (RRC) early data request message. 
     
     
         7 . The UE of  claim 1 , wherein the one or more processors are further configured to cause the UE to receive a subsequent transmission response after transmitting the EDT communication, wherein the subsequent EDT communication is transmitted based at least in part on the subsequent transmission response. 
     
     
         8 . The UE of  claim 7 , wherein the subsequent EDT communication is transmitted in a contention-free resource indicated in the subsequent transmission response. 
     
     
         9 . The UE of  claim 7 , wherein the subsequent EDT communication includes an uplink information transfer message. 
     
     
         10 . The UE of  claim 7 , wherein the subsequent transmission response includes a contention resolution identifier, a radio network temporary identifier (RNTI) to be used for the subsequent EDT communication, information that indicates a set of resources to be used for the subsequent EDT communication, and a timing advance command. 
     
     
         11 . The UE of  claim 7 , wherein the subsequent transmission response includes a plurality of multiplexed medium access control (MAC) packet data units (PDUs). 
     
     
         12 . The UE of  claim 7 , wherein the subsequent transmission response includes a single medium access control (MAC) packet data unit (PDU). 
     
     
         13 . The UE of  claim 7 , wherein the subsequent transmission response includes a radio resource control (RRC) message. 
     
     
         14 . The UE of  claim 1 , wherein the subsequent EDT communication is transmitted in a contention-based resource indicated in a periodic common uplink channel resource. 
     
     
         15 . The UE of  claim 1 , wherein the indication indicates whether the UE will wait for a subsequent transmission response, associated with the EDT communication, prior to transmitting the subsequent EDT communication. 
     
     
         16 . The UE of  claim 1 , wherein the indication indicates that the UE supports transmission of subsequent EDT communications. 
     
     
         17 . The UE of  claim 1 , wherein the one or more processors are further configured to cause the UE to perform an EDT fallback based at least in part on satisfaction of an EDT fallback condition and after transmitting the subsequent EDT communication. 
     
     
         18 . The UE of  claim 17 , wherein the one or more processors, to cause the UE to perform the EDT fallback, are configured to cause the UE to discard one or more successfully transmitted non-access stratum (NAS) packet data units (PDUs). 
     
     
         19 . A method of wireless communication performed by a user equipment (UE), comprising: 
 transmitting an early data transmission (EDT) communication including an indication associated with subsequent EDT communications; and    transmitting a subsequent EDT communication after transmitting the EDT communication, wherein the subsequent EDT communication is transmitted in a transmission occasion based at least in part on the indication.    
     
     
         20 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising: 
 one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to: 
 transmit an early data transmission (EDT) communication including an indication associated with subsequent EDT communications; and 
 transmit a subsequent EDT communication after transmitting the EDT communication, wherein the subsequent EDT communication is transmitted in a transmission occasion based at least in part on the indication.
